  • Patent number: 6716311
    Abstract: The invention relates to modified cationic polymers which can be obtained by reacting (a) water-soluble, polymeric compounds containing NH groups with (b) compounds which are at least bifunctional with regard to NH groups, which contain at least one alkyl radical or alkenyl radical having at least 8 C atoms, and which contain, as a functional group, a halohydrin, epoxide, carboxyl, chloroformate or isocyanate group or a halogen atom. The invention also relates to a method for producing the polymers by reacting the compounds of groups (a) and (b), and to the use of the modified cationic polymers during the production of paper as fixing agents for papermaking stock containing interfering substances.

  • Patent number: 6034257
    Abstract: In a process for preparing an alkoxylated amide of the formula (I)R.sup.1 --CO--NR.sup.2 --CHR.sup.3 --CHR.sup.4 --O--(CHR.sup.5 --CHR.sup.6 --O).sub.n --H (I)(1) glycerides of the fatty acids, specified later on, of the formula (II):R.sup.1 --COOH (II)are reached with amines of the formula (III)HNR.sup.2 R.sup.7 (III)to give amides of the formula (IV)R.sup.1 --CO--NR.sup.2 --R.sup.7 (IV)and glycerol,(2) then the glycerol which has been formed is separated off by adding of aqueous acid solution to the reaction mixture until it has a pH in the range 1-7, in order to bring about phase separation into a glycerol-containing aqueous phase and an organic phase containing amides of the formula (IV), and separating off the aqueous phase, and(3) subsequently the amide of the formula (IV) is reacted with ethylene oxide and/or propylene oxide and/or butylene oxide to give alkoxylated amides of the formula (I).

    Abstract: In a process and an apparatus for the continuous preparation of N-acylamino carboxylic acids and N-acylamino sulfonic acids, and their alkali metal salts, from the alkali metal salts of amino carboxylic acids and amino sulfonic acids, respectively, and carbonyl halides in a reactor designed as circulating circuit, the reactants are fed for immediate reaction into the circulating circuit, and a part of the product solution corresponding to the amount fed in is continuously discharged from the circulating circuit. The reactants are circulated by a circulating pump. The temperature in the reactors is controlled. The heat produced in the reaction is removed.
